IR21571PBF Infineon Ballast Controller | 16-DIP | 600V Half-Bridge, 50% Duty Cycle

Product Overview

The IR21571PBF is a high-voltage, high-speed, self-oscillating half-bridge driver IC designed for electronic ballast and power supply applications. Manufactured by Infineon Technologies, this device integrates a 600V half-bridge driver with a programmable oscillator, providing a compact and efficient solution for driving MOSFETs or IGBTs in resonant converter topologies. The IC features a 50% fixed duty cycle, deadtime adjustment, and under-voltage lockout (UVLO) protection, ensuring reliable operation in demanding environments. Housed in a 16-pin DIP package, the IR21571PBF is ideal for cost-sensitive and space-constrained designs.
